HAGADORN ELMORE-W ATTORNEY 3,084,870 Patented Apr. 9, 1963 ice 3,084,870 SPRAYING APPARATUS Elmore W. Hagadorn, 515 N. Orchard Road, Solvay, N .Y. Filed Mar. 27, 1961, Ser. No. 98,422 9 Claims. (Cl. 239305) This invention relates to paint sprayers or other sprayable fluids and materials, and more particularly to apparatus capable of accommodating a plurality of protective coating materials or other sprayable fluids and materials and arranged for ready selection of any one of the materials at will.

More particularly, the invention has to do with readily portable apparatus for holding a plurality of containers having different coating materials which may be employed in sequence upon a particular job, such as furniture refinishing wherein successive coating of different materials such as oils, lacquers, stains, or a combination thereof. The apparatus is adapted to hold a number of such containers, and to provide means for spraying from any one of the containers at will. The apparatus is adapted for manual operation, and provides for quickly shifting from one container to another, so that an operator may apply successive coatings of different materials in quick succession from a single light weight handy apparatus. The apparatus comprises a container carriage in which containers are readily placed or re placed, and a carriage support having transverse sliding relation to the carriage whereby quick selection of any container may be made.

The above and other novel features of the invention will appear more fully hereinafter from the following detailed description when taken in conjunction with the accompanying drawings. It is expressly understood that the drawings are employed for purposes of illustration only and are not designed as a defiinition of the limits of the invention, reference being had for this purpose to the appended claims.

In the drawings, wherein like reference characters indicate like parts:

FIGURE 1 is a plan view of one form of the dispensing apparatus;

FIGURE 2 is a section taken substantially on the line 2-2 of FIGURE 1;

FIGURE 3 is a fragmentary enlarged sectional view taken on the line 3-3 of FIGURE 1 showing the carriage detent;

FIGURE 4 is a fragmentary sectional view taken through a container cap, substantially on the line 2-2 of FIGURE 1; and

FIGURE 4A is a fragmentary sectional view taken through a modified container cap as on the line 4A4A of FIGURE 1.

Referring to FIGURES 1 and 2, there is shown a container containing compressed gas, partially in a liquified state under pressure, if desired, for spraying in atomized form, a paint or lacquer, or other active material in liquid form from any one of the containers such as 12, 13, 14, or 16. The container 10, has a reduced diameter cylindrical portion 20, adjacent an annular inclined shoulder 22, adapted to be fixedly positioned in a carriage support or collar member 24, the aperture 25 being disposed around the cylindrical portion 20, and seated against the shoulder 22. The collar may have an easy sliding fit over the container cylindrical portion 20, so as to permit ready replacement of the container 10 from time to time. A thumbscrew 26 threaded in the collar, and having a clamping end 28, is adapted to bear against the container portion 20, and releasably secure the container 10 in position.

One edge of the collar is provided with a dovetail section ridge 32 slidably disposed in a complemental elongated channel member 34- forming a part of a container carriage. The member has a flange 36, which embraces one corner of a rectangular sectioned rail 38, the lower edge 40, of which may bear against the cylindrical body portion 42 of the container 10, below the shoulder 22. Suitable fastening means such as screws 4d, and 46 may be provided.

The rail 38 is provided with an elongated angle iron bracket 50 on its outer face, the bracket extending parallel with the channel member 34, and having one flange 54 thereof secured to the rail as by screws 52. The other flange 56 of the bracket member extends at right angles to the flange 54, and is provided with a plurality of preferably uniformly spaced U-shaped recesses 58, adapted to snugly receive the neck portion of the containers such as 12-16 inclusive.

Each container, such as 12 comprises a relatively flat annular shoulder 60' from which there extends upwardly an externally threaded neck 62, which normally is provided with an internally threaded cap, having a sealing gasket as will be understood in the art. Each of the containers 112-16 inclusive, after removal of the aforesaid cap (not shown) are provided with a nipple assembly comprising a nipple 64 having a flange 66 seated beneath the flange 68 of an internally threaded ferrule 70, which is externally knurled as at 72. The ferrule may be rigidly secured to the nipple, and is adapted to be threaded upon the container neck 62 so as to clamp a container upon the flange 56 in a recess 58 in a fixed position along the length of the rail, and with the container body portion 63 bearing against the rail 38. When so fixed in position, the tip end 73 of the nipple 64 having a suction discharge aperture 74, is disposed at a uniform height in regard to the channel member 34 and in respect to the nipples 64 of the other containers. Each nipple is provided with a suction tube 76 reaching substantially to the bottom of the container.

The head end of the container 10 is provided with a fluid pressure valve 80 having a lateral discharge orifice 82 into which is affixed, as by threads 84-, an elongated nozzle 86. The valve plunger 88 is adapted to be depressed by finger pressure applied to the finger operating lever 90 pivoted to the valve body as at 92. The nozzle 86 is of a length to discharge gas in the plane of the tips 73 of the nipples of the containers 12-16 inclusive, immediately adjacent thereto. The gaseous discharge stream playing across the orifice in the nipple tip creates a vacuum area, resulting in lifting the liquid contained within the container 13 into the vacuum creating discharge stream, and resulting in atomization of the liquid so lifted. To maintain atmospheric pressure within the containers 12-16 inclusive, a small port such as 97 in the ferrule of each nipple assembly may be provided.

In order to provide for conveniently spraying the contents of any one of the containers 12-16 inclusive, as desired, the rail 38 is slid along the dove tail projection 32 of the collar 24, so as to locate the nozzle 86 in the vertical plane of any one of the nipple apertures 74 of one of the selected containers 12-16 inclusive. In order to facilitate proper location of a container, such as .13, with the nozzle 86, a ball detent 98, adapted to engage shallow recesseses .100 in the channel member, is located in an aperture 102 in the collar member 24. The ball is backed up by a coil spring 104, providing suitable pressure on the ball to provide a lock at any position of alignment of the nozzle with a nipple of a container such as 12-16 inclusive, by the inter engagement of the ball with one of the recesses 100. Such recesses may be shallow, and the spring of sufficiently light tension to permit ready shifting of the rail to position and accurately locate and yieldingly hold any one of the containers with its nipple in the vertical plane of the nozzle 86. The screws 46 may be so located as to provide stops, to limit the travel of the rail to end positions in which the nozzle 86 is iligned with the nipple 64 of the end containers '12 and A finger 103 secured to the collar member 24, may be provided to extend over and bear upon the flange 36 whereby to assist in maintaining alignment of the collar member dove tail 25 with thechannel 32.

-In FIGURE 4, the cap or ferrule 70 is shown clamped upon the support flange 56. If desired, the threaded cap may be employed as in FIGURE 4A as a means of adjusting the height of the discharge aperture or orifice 74 in reference to the nozzle or jet 86, so as to obtain optimum aspiration and spraying conditions. In FIG- URE 4A the neck 62 of the container 16 which may be formed of plastic is provided with an annular head 55 forming an annular groove 57 adapted to be frictionally alfixed in the U-shaped recess 58, of the flange 56 leaving the cap 61 and nipple free to be threaded up or down slightly on the threads 67 of the bottle neck, so as to adjust the level of the orifice in reference to the jet 86, which for illustrative purposes in FIGURE 4A is shown in side elevation.

It will be seen that the dove tail section ridge 32 constitutes a key interlocking in sliding relation with the channel sectioned key way 34.

While a single form of the invention, has been referred to, it will be understood that the invention is not limited thereto. As various changes in the construction and arrangement may be made without departing from the spirit of the invention, as will be apparent to those skilled in the art, reference will be had to the appended claims for a definition of the limits of the invention.
